That's not entirely true Pammie although it is difficult to see who you think will "flag up" what.
The bank will do a download of the account. They will not be involved with any analysis. They will perform a simple data dump of everyone's account where at least one description contains your National Insurance number. They will send the data electronically to the DWP. The DWP will use their software to analyse this.
Will their programme efficiently remove those only receiving the State Pension? Will they destroy that data? It is not illegal for them to use that data or forward it to another department.
Who will supply the analytical programme to find the "anomalies"? We know the government has continued to use Fujitsu since the issues have been uncovered.
What will be the approach of the DWP? The Post Office, supported by Fujitsu, put the recovery of so-called "losses" ahead of the law. We have seen this happen already with PIP, etc.
Now the Post Office has had to open their books, we can see just how wrongly the Post Office law enforcement team has behaved. Why should we have any more trust in another private law enforcement team when we know "he who pays the piper calls the tune"? Why would any of the under-experienced, underqualified and under-trained force do any better than POL?
The Post Office prosecutions were said by those representing some of the Sub-postmasters to be" deeply and fundamentally flawed". What will be the management and oversight? It is already biased towards the reputation of the DWP and its "successes".
Who will support those picked up by the software, and how will they get the information they need? The Post Office denied legally supported access to information. The Post Office have been ^"wilfully blind to, or disregarding of the proper lawful administration of justice". Many people feel the DWP is already behaving in this way.
If the Police knock on your door, there is a separate Police Complaints Office you can go to. There was no such separate entity to hold the Post Office law enforcement body to account. For its victims, it was rather like living in the Wild West.
There is no such body to hold the DWP to account either.
